The mechanisms of toxicity to isolated rat hepatocytes of two structurally related naphthoquinones have been studied. Both 5-OH-1,4-naphthoquinone (5-OH-1,4-NQ; juglone) and 2-OH-1,4-naphthoquinone (2-OH-1,4-NQ; lawsone) caused a concentration-dependent cytotoxicity to hepatocytes which was preceded
